I did 300+ in a out a half hour. Fun game with a buddy or two, take a deck of cards, numbers represent how many pushups you do, jack 15 queen 20 king 25 ace 30. Flip a card and do the pushups, your only rest is the other peoples turns.

Ha ha, that would be fun but at that rate my muscles lock up and can't physically move. I know it made my gym teachers mad, and some people don't understand how this can be real, but even when I feel strong and ready to do more reps, the muscle just turns to stone and cannot move. It might be genetic.
